But isn't every single match of the World Cup televised? Why couldn't they institute instant replay just for the World Cup matches. The qualifying rounds could be played without it. Two referees on the field should be a must for any match as far as I'm concerned.

The rest of the world probably won't agree with me, but there should be some sort of time out system applied as well. The fact that players have to fall on the ground and pretend they're injured just to give their team a chance to catch their breath and get some water is appalling. I can't believe it's considered good strategy to fake an injury. This is the number one reason why I cannot watch this sport and enjoy it.
